Frequently Asked Questions
What do I get after processing?
Each job returns downloadable files for the output you selected. Depending on the task, that can include an editable Guitar Tab file, with Guitar and Backing track audio added for full-mix Tab jobs; stem audio packs; DAW-ready MIDI; and PDF score drafts + editable MusicXML.
What audio formats are supported?
MP3, WAV, FLAC, M4A/AAC, OGG, AIFF, and most common formats. If something needs conversion, the app handles it automatically.
How is processing handled?
Jobs run through Music Demixer's secure cloud service to generate your outputs quickly and reliably. You upload once, then download the files for your workflow.
Is there a free plan?
Start with one Free Preview job, including downloads from a representative segment. Buy a 5-job Pack or subscribe to Pro to process more jobs and download full-length results.
How do I convert MP3 audio into MIDI files?
Upload MP3 or WAV from a song, stem, or solo recording, then run the MIDI workflow. You receive Original Timing MIDI for syncing with the recording and Beat-Aligned MIDI for editing against the detected score grid.
Can I start from a full song or a stem?
Yes. Start from a full song when you want Music Demixer to prepare the selected part in the workflow, or upload a stem or solo recording when you already have one. Piano and drums use the most specialized MIDI paths; other parts are pitch drafts for cleanup.
Can melodic vocals be converted to MIDI notes?
Yes. Melodic vocals can become useful pitch drafts. Vibrato, doubles, and harmonies often need cleanup after import because the vocal note draft is less specialized than the piano and drum paths.
Can guitar or bass be converted to MIDI?
Yes, guitar riffs and bass lines can become editable pitch drafts. Heavy distortion, overlapping notes, and complex articulation usually require cleanup after import.
Why does the MIDI draft sound simpler than the original audio?
MIDI captures note events, not the full texture of the recording. Timing, overlap, articulation, and voicing often need cleanup once you import the file into your DAW.
What audio can I upload for MIDI transcription?
Upload audio you're authorized to use. You're responsible for copyright and licensing compliance in your jurisdiction.
Can I use the output commercially?
Yes, if you own the rights to the input audio or have permission or a license, you can use the outputs commercially.
MIDI Files for Editing in Your DAW
Convert one selected musical part into editable MIDI instead of flattening a full song into one arrangement draft.
Where transcription is strongest
- Piano uses the most specialized melodic transcription path.
- Drums uses a dedicated rhythm and percussion path.
- Guitar, bass, vocals, hooks, leads, and Other produce pitch drafts for cleanup.
Start from a song, stem, or solo recording
Use a full mix when Music Demixer needs to prepare the selected part, or start directly from a stem or solo recording. After Stem Separation, continue from a result without uploading the song again.
What the MIDI file gives you
The download is an editable MIDI file for Ableton Live, Logic Pro, FL Studio, GarageBand, Cubase, REAPER, or another DAW. Timing, note lengths, octave placement, overlap, and voicing can need adjustment after import. Choose Sheet Music instead when you need a PDF score and editable MusicXML.
Generate MIDI for the Part You Want
Start from a song, stem, or solo recording. Music Demixer can separate before transcription when that workflow fits.
